REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : CNS 1.2 REMARK 3 AUTHORS : BRUNGER,ADAMS,CLORE,DELANO,GROS,GROSSE- REMARK 3 : KUNSTLEVE,JIANG,KUSZEWSKI,NILGES,PANNU, REMARK 3 : READ,RICE,SIMONSON,WARREN REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: STRUCTURE CALCULATION INCLUDED DISTANCE REMARK 3 RESTRAINTS BASED ON PARAMAGNETIC RELAXATION ENHANCEMENT REMARK 3 DATA FROM TEN INDEPENDENT CYSTEINE MUTANTS (N155C, A164C, REMARK 3 A171C, L187C, A188C, T209C, D273C, S281C, A287C AND A318C) REMARK 3 COVALENTLY MODIFIED BY 3-(2-IODOACETAMIDO)-2,2,5,5, REMARK 3 TETRAMETHYL-1-PYRROLIDINYLOXY RADICAL (IODOACETAMIDO- REMARK 3 PROXYL). THE STRUCTURE WAS DETERMINED USING A MULTI-STEP REMARK 3 PROTOCOL. FIRST WITH REFINEMENT OF INDIVIDUAL STRUCTURED REMARK 3 DOMAINS FOR RRM1 AND RRM2 OF U2AF65. THE INITIAL REMARK 3 COORDINATES OF THE ISOLATED DOMAINS WERE BASED ON PDB ENTRY REMARK 3 2G4B BY SICKMIER ET AL. 2006 (SEE REMARK 1 REFERENCE). SECOND REMARK 3 STEP WAS ADDITION AND RANDOMIZATION OF FLEXIBLE AND LINKER REMARK 3 RESIDUES. THE THIRD STEP WAS MODEL CALCULATION USING RDC REMARK 3 ORIENTATION, PRE-BASED DISTANCE, TALOS DIHEDRAL AND REMARK 3 HYDROGEN BOND RESTRAINTS WITH THE RRM1 AND RRM2 DOMAINS REMARK 3 RESTRAINED TO THEIR INITIAL STARTING STRUCTURES. INTER- REMARK 3 MOLECULAR PROTEIN-RNA DISTANCE RESTRAINTS WERE BASED ON REMARK 3 ATOMIC DETAILS FROM PDB ENTRY 2G4B AND ASSUMED AN EIGHT- REMARK 3 URIDINE BINDING MODE FOR U2AF65 RRM1-RRM2.
